Pinion angle

[Dion Hildebrandt]

So I have been destroying driveline parts and am going to get a Mark Williams drive shaft, but I am also trying to dot my i's and cross my t's to figure out any contributing factors. My Question is this in the attached links below in regards to pinion/operating angle they seem to contradict each other, what is the ideal setting of the driveline?. In my car I have the tranny 5 degrees down(-)as OEM and the pinion down 1 degree(-) as recomended by the suspension supplier. In the Buick tech link the author talks about the driveshaft being zero and all angles added together for the total number which should be less than 15 degrees. The M/W link says the tranny and pinion should be opposite (one down(-) and one up (+) )of each other. So that would mean i should have my pinion set at 5 degrees up (+) right? that seems back assward to me as the pinion would move up under load exagerating the setting am I wrong?
